An Olympic high diver has gravitational potential energy because of her height. As she dives, kinetic energy becomes of her energy just before she hits the water.

Gravitational potential energy is the energy possessed or acquired by an object due to a change in its position when it is present in a gravitational field. In simple terms, it can be said that gravitational potential energy is an energy that is related to gravitational force or to gravity.

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles.

When the high diver is standing stable and not moving , that diver has a gravitational potential energy because of the height . The moment she dives , before hitting the water , from being stationary she gained some momentum and come in motion , due to motion her gravitational potential energy will change to kinetic energy before hitting the ground.

Answer:

The average U.S. home uses about 11,000 kilowatt hours of electricity per year.

Electricity travels at the speed of light – over 186,000 miles per second.

Electricity can be produced from fossil fuels, large hydro power plants, nuclear power plants, or renewables like wind or solar.

Birds and other small animals can perch on power lines without being electrocuted unless they simultaneously touch another line, which would create a complete circuit.

For electricity to come into your home, it travels from generation facilities to a high-voltage switchyard, to transmission lines, to a substation, to a distribution line, to a transformer, to your house.

Geothermal energy comes from the Earth. It consists of hot water and hot rock that’s just a few miles beneath the Earth’s surface, and can go even deeper to very hot molten rock called magma. It’s considered clean and sustainable.

Renewable energy comes from perpetual sources like wind, solar or geothermal. Most electricity, though, is produced from nonrenewable sources like fossil fuels (coal, crude oil, natural gas, and uranium). They are nonrenewable because there is a finite amount of them that were formed from buried remains of plants and animals that lived millions of years ago. They cannot be replenished the way renewable energy sources can.  

In the U.S., the areas most favorable for geothermal energy use are in Nevada, Oregon, Idaho, Arizona, Utah, Colorado and New Mexico. Geothermal plants are located where water has seeped into the Earth’s crust, and they force the water back up through permeable rock.

Saving energy can be as simple as switching from incandescent light bulbs to CFL or LED versions.  

About 40 percent of energy from all resources is used for electricity, which means that our resources are used more for that purpose than for any other.

 

CFL bulbs consume 80% less electricity than standard bulbs

Natural Gas Facts

When we think about energy facts, we usually focus on electricity, but our homes use natural gas, too! Natural gas is a gaseous mixture of hydrocarbon compounds used as fuel to generate electricity. In order to be used in your home, it must first be processed and converted into dry natural gas. To learn more about its use in your home, check out the natural gas facts below.

 

10 Facts about Natural Gas

The main component of natural gas is methane, with butane, propane, ethane, or pentane sometimes included.

The “rotten egg” smell of natural gas is actually added by power companies so that your nose can detect a gas leak. In its initial state, natural gas is colorless and nearly odorless.

Most natural gas is delivered via pipeline; there are enormous networks that deliver it to processing facilities, which then transport it to the end consumer. Along the route, there are compressors and metering stations to monitor pressure, flow, and leaks.

When natural gas is transported between countries, it travels by ship in liquid form. This way, it takes up less volume. Once it reaches land, it is regasified (or returned to gas form) and sent to the pipelines for distribution.

In the U.S., there are more than 2.5 million miles of pipeline used for transporting natural gas directly into homes and businesses.

It’s reported that 85 percent of the natural gas consumed in the United States is produced domestically.

Energy facts suggest that natural gas is one of the cleanest choices for fossil fuels. It produces less carbon and pollution than other fossil fuels.

The natural gas and oil industry employs nearly 10.3 million Americans. That’s equals to about 5.6 percent of all of U.S. employment.

Approximately 66 million homes and 5 million businesses in the U.S. use natural gas as an energy source.

This is one of the more important natural gas facts: transportation is one of the most difficult and fragile aspects to its use. Because the main component to natural gas is methane, which is a potent greenhouse gas, undetected leaks can contribute to climate change.  

The "rotten smell" is added to the natural gas so your nose can detect a gas leak

A- 1000 m/s2<br> Xi-0m<br> Xf-0.75m<br> Vf-?
sleet_krkn [62]

Answer:

The final velocity of the object is,  v_{f} = 27 m/s    

Explanation:

Given,

The acceleration of the object, a = 1000 m/s²

The initial displacement of the object, x_{i} = 0 m

The final displacement of the object,  x_{f} = 0.75 m

The initial velocity of the object will be, v_{i} = o m/s

The final velocity of the object, v_{f} = ?

The average velocity of the object,

                                    v = ( x_{f} - x_{i} )/ t

                                      = 0.75 / t

The acceleration is given by the relation

                                     a = v / t

                                   1000 m/s² = 0.75 / t²

                                            t² = 7.5 x 10⁻⁴

                                            t = 0.027 s

Using the I equation of motion,

                                  v_{f} = u + at

Substituting the values

                                   v_{f} = 0 + 1000 x 0.027

                                                           = 27 m/s

Hence, the final velocity of the object is,  v_{f} = 27 m/s

Prior Knowledge Questions (Do these BEFORE using the Gizmo.)A buoy is anchored to the ocean floor. A large wave approaches the b
dimaraw [331]

Answer:

bounce up and down

Explanation:

Buoys are used for two main reasons, one is to let the people on land know of a big incoming wave, while the second reason is to generate electricity. When a big wave is approaching the buoy starts to bounce up and down with the strength of the smalled previous waves and then bounce very strongly up as the bigger wave passes by. This movement is combined with pistons within the buoy in order to conduct electricity.
